How you'll learn
100% online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, which makes it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is KISSsoft, SolidWorks, MATLAB/Simulink, MSC Adams, in free, academic or evaluation versions. Tests are studied using real procedures from transmission test benches, off-road test tracks, and vibration and noise analysis. Assessment is continuous, module by module, plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Compare permanent, part-time and automatic four-wheel drive architectures.
Analyse the operation of transfer cases and their low-range gearboxes.
Calculate solid axles and axle assemblies under off-road service loads.
Select mechanical, pneumatic or electronic differential locks.
Size driveshafts and constant-velocity and cardan joints.
